gaodayue edited a comment on issue #3269: Optimize performance of TxnManager::build_expire_txn_map URL: https://github.com/apache/incubator-doris/pull/3269#issuecomment-610223198 > By the way, could you please add some label to this PR, like performance and storage engine? Sure, added. > And do you have any improvement data resulted from this PR? Not yet. The background for this PR is that we independently found and solved the issue of #2214 which could decrease the tablet report time from 30s to 1s. When submitting the PR, I found that it's already addressed by #2215. So I compared our patch with that PR and found that our version which use vector instead of set may be better.
